If finances permit, wouldn't it be easier to just go ahead and buy an O/A torch and bottles? Or perhaps an O/propane torch.That way you only have to buy/lease one expensive tank.
Just a suggestion,

PS: If you know someone that has a hyd press,you can make these bends cold.

I bought one of those oxy/mapp torches a few months back.
I was not impressed with it at all.
I am practicing my welding. So far all I can do is make big blobs of metal slag.
I did manage to get my test pieces to stay together twice.
The little oxy/mapp torch would not cut them apart.
Luckily, lowes has a good return policy.
Gonna save my money for a small oxy/propane or o/a set up.
Until then, I'm gonna try the little forge setup to bend this.

Your clay pot forge will work surprisingly well, but you'll burn up a few bucks of charcoal briquets making it all happen. If you can get some cokeable coal you'd prefer it.

If you have a shop vac or blower you can get plenty of air. Only problem I see is that you need a bigger hole in the bottom of the clay pot. Three inches would be great. Two would work, smaller becomes more marginal. (You want to move a largish quantity of air not too fast, or the air flow will actually disrupt and cool the fire and blow the coals out of the fire.)

If you can get a copy of "PRACTICAL PROJECTS FOR THE BLACKSMITH" by Ted Tucker, Rodale, 1980, you will see how to make a small cheap forge for almost nothing. A small one can be made with a gallon can, if you're just using it once.

Heat the steel to a nice orange color. You can hold on to the long end with your hand, but you'll need something to grip the hot end. You could probably do this with a pair of vice grips, but I'd lay it over the edge of the anvil (in your case any fairly heavy, straight piece of steel) or clamp it in the vice right where I wanted the bend to form, and then apply pressure -either with the hammer (gentle, persistent rapping blows) or by grabbing that cool, long end and pulling. This would let you locate that bend just where you liked. If need be you can punch the steel a little when cold to give you marks you can find when it's all hot.

Try to be decisive. Although you can fix any errors it's a whole lot easier to just get it right at once, and you have enough time. The 1/2" will hold heat for a reasonable period, and you can always go back to the fire for more.
